Gates Hopeful of Improved China Relationship VOA News 12 January 2011 U.S. Defense Secretary Robert Gates talks while visiting the Great Wall in Mutianyu, China, 12 Jan 2011 Photo: AP U.S. Defense Secretary Robert Gates talks while visiting the Great Wall in Mutianyu, China, 12 Jan 2011 U.S. Defense Secretary Robert Gates has wrapped up his four-day trip to China saying he found both civilian and military leaders ready to carry the U.S.-China relationship to the next level. Gates spent Wednesday touring the nation's nuclear command center and visiting the Great Wall north of Beijing before flying to Japan. He will be in South Korea Friday. Gates said he enjoyed candid conversations with commanders at the nuclear warfare headquarters, including a discussion of China's nuclear strategy. He said the commander of the facility in Qinghe, outside Beijing, has accepted an invitation to pay a return visit to the U.S. Strategic Command headquarters in the U.S. state of Nebraska. Gates said he was pleased with the results of his visit, which was intended to restore direct contacts between the two militaries with a goal of avoiding misunderstanding and miscalculations. He said he believed his meetings had "set the stage for taking the military-to-military relationship to the next level." The major surprise of the visit was China's decision to conduct the first test flight of its prototype stealth jet fighter on the same day Gates was meeting with President Hu Jintao. A senior U.S. official said Mr. Hu and his civilian aides appeared not to be aware of the test until the Americans questioned them about it. That prompted speculation about a split between China's civilian and military leadership. But Gates said Wednesday he did not detect a rift. He said, "What came across to me was that both the civilian and military leadership seem determined to carry this relationship further and to build upon it." During his talks with Mr. Hu on Tuesday, Gates asked for China's help in getting North Korea to abandon its nuclear and intercontinental missile programs, which he said can pose a threat to the United States within five years. Gates is expected to hold further discussions on North Korea in Tokyo and Seoul. Some information for this report was provided by AP, AFP and Reuters. .
